Will I get reproducible results using this torque wrench?
Tests have shown that for a given torque value applied, the difference of indentation between 2 gaskets is less than 5% making this tool and method reproducible.
What is the advantage of using this tool compared to simple Allen keys?
Using a torque wrench allows the user to apply the same torque value on each clamping screw. It provides a more controlled and importantly quantified torque on the clamping screws. Using simple Allen keys only provide a coarser method.
